The GranTurismo Convertible is a dynamic and elegant convertible for four.

The Maserati GranTurismo Convertible succeeds in being both dynamic and elegant. The car draws its inspiration from the GranTurismo performance Coupe, an example of the perfect synthesis of modernity, sensuality and passion of Maserati SpA in Modena, Italy.
Created by master coachbuilder Pininfarina, the GranTurismo Convertible is characterized by its soft-top roof. This styling closely connects the GranTurismo Convertible with the company’s history of refined design of over 90 years
When closed, the roof follows the original contours of the GranTurismo Convertible, with a hood that has the same V-shaped, forward-slanting design, giving the GranTurismo Convertible the dashing looks of the stunning Maserati coupé.
Once open, the Maserati GranTurismo Convertible transforms into a striking cabriolet, free to demonstrate its seamlessly balanced design and beauty. The vibrant profile is accentuated by the low ground clearance and long hood design. A stylish ‘V’ points towards the grille, in the middle of which stands the legendary chrome Maserati Trident.
The vehicle sides also feature chrome elements that give the GranTurismo Convertible added distinction. One particular design feature is the continuous chrome trim segment that surrounds the cabin and integrates with the third rear stop light. This design element signifies the Maserati passion for excellence – even in the details.
Towards the rear of the car, the triangular light units are formed by 96 LEDs which contain a wide diffuser that further underlines the car’s athletic poise. This sporty feel is also seen in the large, 20” alloy wheels that reflect the legendary Birdcage racing design of the 1950’s which was the first lightweight spaceframe chassis ever produced. .
The shape of the GranTurismo Convertible is the result of extensive aerodynamic testing aimed at limiting the drag typical of drop-top cars. The GranTurismo Convertible boasts a Cd (Coefficient of drag) that is one of the best in its class: 0.35 with the hood up and 0.39 with it down. The spoiler and rear diffuser both contribute to obtaining top levels of roadholding up to a top speed of 173 mph.

Interior

The GranTurismo Convertible’s cabin offers the maximum in comfort for front and rear occupants.

The Maserati GranTurismo Convertible is the only drop-top in its class to offer properspace for four adults, seated in an elegant and luxurious cabin. The interior space is significantly larger than other vehicles in this exclusive category and ensures the maximum comfort even for rear passengers.
The interior is divided by a central tunnel distributing space between the occupants along the car’s length. The dashboard extends horizontally and its upper section features a characteristic ‘V’, a distinctive Maserati design symbol.
Only the finest materials were employed in the GranTurismo Convertible’s aesthetically-designed cabin: the leather was handcrafted by Poltrona Frau® and a selection of prestigious wood trim was used for the dashboard, door panel and rear areas. The level of craftsmanship and attention to detail can also be seen in the chrome rings that enhance the dashboard switches and steering wheel. Alcantara sections meeting the fingertips on the back of the steering wheel shift paddles are a tactile confirmation of this vehicle’s quality.
Adding to the on-board comfort is the insulated canvas roof, one made up of three layers to ensure quietness through excellent acoustic isolation. With the top down and with just two on board, it is possible to further minimize interior air flow thanks to an optional windstop developed specifically for the GranTurismo Convertible.
The Maserati GranTurismo Convertible air conditioning system has been further refined to offer the maximum comfort levels with the top up or down. The system recognizes how the car is being driven, and automatically resets ventilation and climate control to help maintain the set temperature.

Technology

Maserati GranTurismo Convertible: Engine, transmission, chassis, suspension and electronics

Engine
The engine of the Maserati GranTurismo Convertible is an eight cylinder, 4,691cc 90° V-8, capable of developing 433 bhp at 7,000 rpm with a peak torque of 361 ft-lb at 4,750 rpm. The power unit uses advanced technology typical of all Maserati engines allowing the high power figures to be reached, while ensuring smooth gear changes and a refined engine exhaust note.
The engine valvetrain is actuated by two overhead camshafts per cylinder bank with four valves per cylinder controlled by hydraulic tappets. The overhead camshafts on the intake side are controlled by a low oil-pressure activated continual phase variator, a technical solution that, together with the optimization of the cylinder combustion chambers, allows 82% of the maximum torque to be available from 2,500 rpm for superb acceleration, even in high gears.

Transmission
The Maserati GranTurismo Convertible features a six-speed, ZF automatic transmission with a hydraulic torque converter yielding extremely quick and fluid gear shifts while maintaining the characteristics of the sporty V-8 engine.
The transmission has four modes and is also equipped with a self-adapting control system that adjusts gear changes to both the driving style and road conditions.
In Manual mode, gear changes are made sequentially by the driver via the standard steering column-mounted paddles or the gear shift lever.

Exhaust
The engine sound is enhanced by the sport exhaust system including a special by-pass valve. Pushing the Sport button opens the pneumatic valves if the car is on the move and the engine is above 3,000 rpm. The engine and driveline are fully ready to deliver a rewarding engine roar which becomes even more intense with the roof open, bringing the GranTurismo Convertible at one with the environment.

Chassis
The weight distribution of the Maserati GranTurismo Convertible is slightly biased towards the rear with 49% of the vehicle’s weight located over the front axle and 51% over the back with the roof closed. With the roof retracted, the front-rear distribution changes to 48-52%.
This design result was achieved by locating the engine behind the front axle and results in true and predictable handling that makes driving easier and increases car stability and control.
The new loadbearing body structure is constructed from a blend of materials with the overriding goal to maintain low weight. The vehicle framework is made from toughened steel apart from the hood and front bumper support, which consist of aluminum, and the trunk lid in heat treated plastic that uses Sheet Moulding Compound technology.
The chassis was developed to provide maximum stiffness even as a cabriolet without a fixed roof. The result is that the Maserati GranTurismo Convertible is able to offer the same driving pleasure as a high performance coupe.

Suspension
The Maserati GranTurismo Convertible is fitted with an electronically-controlled Skyhook suspension as standard equipment. This system employs dampers with an aluminum body which continually adjust the damping. This solution means that the calibration adapts instantly to the driving style and the road conditions to offer the utmost in on-board comfort.
The Skyhook system acts by using acceleration sensors that detect movement on all four wheels and the body. A control unit processes the data it receives from the sensors, analyzes the driving style and road surface and instantly adjusts the dampers accordingly via their proportional valves. The result is incredibly responsive handling and precise ride.

Electronics
The car’s superb dynamic handling is constantly monitored and optimized by the Maserati Stability Program (MSP). The MSP works to correct even the onset of a skid by reducing engine torque. Working further with the ABS antilock brakes, the system prevents the wheels from locking under hard braking, and distributes the braking force between the front and rear axles. It also prevents wheel-spin on low grip surfaces when accelerating or climbing (using ASR and MSR) to maximize available traction.

Cabriolet Soft top
The Maserati GranTurismo Convertible’s canvas roof was chosen for both its technological as well as aesthetic advantages. The resulting soft top solution yields a lower center of gravity since the material and design is lightweight adding only 143 lb to the overall GranTurismo Convertible weight. This design enhances the car’s dynamic handling by keeping the weight bias as low as possible.
The lightweight roof materials, from its exterior to the heated back glass window, to its mechanism, operation time and stowage are all top quality. The GranTurismo Convertible transforms from an amazing coupé into a cabriolet in just 24 seconds if the car is travelling up to 20 mph.

Safety

The Maserati GranTurismo Convertible boasts a range of innovative safety features

The Maserati GranTurismo Convertible reaches the highest safety standards in its category thanks to the adoption of innovative active and passive safety features.

Active safety
The dynamic handling of the GranTurismo Convertible is assisted by the electronically controlled Maserati Stability Program (MSP). This technology was developed to optimize driving dynamics and safety when underway. The system is controlled by a series of sensors that recognize vehicle instability, adjusting the brakes and engine to provide optimal traction and vehicle control.
The high performance brakes equipped on the GranTurismo Convertible were developed by Brembo and feature four ventilated and cross-drilled discs. The 360 mm (14.2 in.) front brakes make the most of dual-cast disc material technology (cast iron for the braking surface combined with an aluminum hub). This solution, teamed with six-piston aluminum brake calipers ensure unbeatable stopping power and are highly resistant to fade even under intense use.
MSP works in harmony with the ABS to prevent the wheels from locking under heavy braking, and EBD, to distribute the braking force between the front and rear axles.
The Electronic Parking Brake (EPB) replaces the traditional mechanical handbrake with an electronic control on the vehicle’s central tunnel. The EPB system is engaged automatically when the engine is switched off and is only deactivated when the accelerator pedal is pressed. EPB also plays an important role in terms of safety as, in an emergency, it acts on all four wheels and can be employed with the vehicle moving, without compromising stability, until the switch is released.
The Brake Assist System (BAS) has also been introduced on the Maserati GranTurismo Convertible to improve safety. Thanks to a dedicated sensor, BAS recognizes panic braking by measuring the speed at which the brake pedal is depressed and actuates braking even before the driver has started to brake. This shortens the stopping distance in emergency situations.

Passive safety
The Maserati GranTurismo Convertible is fitted with new generation airbags, using the intelligent technology first employed on the Maserati Quattroporte S. The passenger side airbag, with its ‘Low Risk Deployment’, adapts the intensity of its inflation in crash situations to the size of the occupant.
New head and chest airbags set in the front seats provide protection from side impacts while seatbelts are equipped with the latest pre-tensioners and load limiters to securely restrain all four occupants.
The main components in terms of passive safety on the GranTurismo Convertible are the deployable roll bars set behind the rear seats. The roll bars are hidden by the roof cover and are automatically activated in only 190 milliseconds when needed.
The deployable roll bars were developed to offer occupants the maximum protection both with the roof closed or retracted. A Maserati patented technical advance allows the roll bars to extend upwards by shattering the rear window with minimal risk to the occupants from this precise actuation.

Personalization

The GranTurismo Convertible introduces new personalization options to the Maserati range.

Maserati offers a personalization program that is unlike any other in the world. This program has been developed with the objective of allowing each client to create a made-to-measure car. Such a level of exclusivity is a source of pride for Maserati, a small company able to devote the highest levels of care and attention to every car it builds and guarantee the client a wider range of finishes than its competitors.
The personalization options on the GranTurismo Convertible have been enhanced by the soft top roof, available in six colors, and through the introduction of two new Poltrona Frau® leathers, Bianco Polare and Blu Profondità. The colors are available on the Maserati range for the first time and were selected for their harmony with the exterior paint colors and soft top.
The interior dashboard, door panels and rear side panels are available in a new ‘Dark Chrome’ standard color but it is also possible to choose from various lacquer finishes or precious woods, among them, Carbalho and Moonwood.
In terms of the controls, there are two available finishes for the alloy wheels (Silver or Mercury Gray) and six colors for the brake calipers. Red painted calipers are standard equipment.

The Car Configurator
